She has now told WWD that her response when she was offered the deal was: "F**k yeah!"

"It's an honest collaboration," she said. "I'm proud to be a part of [the brands I'm involved with] because what they do is really cool, especially Givenchy - they're so artistic. And I feel like I have a foot in the fashion industry now."

However, Seyfried explained that she picks her fashion campaigns carefully and suggested that she will not be launching her own fragrance.

"They're hard work, and the more you do, they take away from your work as an actor," she said. "I'm doing these two campaigns because I care about them and the people involved. They're great things to be attached to."
